"Android OS" is top battery consumer after night

Hell,
After 13 hours on battery, "Android OS" is top battery consumer on my Gingerbread device. I understand there is some kind of bug in Gingerbread causing this behavior, but I already pulled battery out and put back in before. Am I supposed to do it every reboot, or how do I fix this annoyance?

Which Gingerbread variant? There are unfortunately multiple causes for this and it can be a ***** to debug. I had it happen for a few days with CM7, but I think it may have been a side effect of the Bluetooth fix breaking GPS, making anything layered over GPS unhappy.
Apparently for some people it's caused by a corrupt SD card that causes mediascanner to go nuts, and on the Nexus S it was caused by people setting Wifi Sleep Policy to "screen turned off" - yes, setting it to "never" would actually save you battery. But at least on CM7, setting wifi sleep policy to "screen turned off" is OK.

It's Infused V2 2.0.3 version

Try setting "WiFi sleep policy" to "Never" and then turn off wifi.
Yes - it seems weird but according to some of the Nexus S reports, even with wifi off the sleep policy mattered.
NOTE: This may do absolutely nothing. As I said, there are multiple things that could cause this. But there have been a lot of reports of wifi causing battery drain on Infused v2.

My WiFi sleep policy is already "Never" but WiFi is on the whole night. Since it's both saves data and battery according to reports.

I have this problem occasionally and it is always fixed (until it comes back :/) by a simple reboot. I'm pretty sure it's the same problem detailed here that GS2 users had and was eventually fixed by some unknown code change from Samsung.
Basically we just need to hope that when ATT releases GB for Infuse it will have the fix in it.

my problem on infused v2.0.4 is that my cell standby eats up most of my battery... about 35% when i got out of school. is there any way to fix this?

It's fixed in 2.3.4.

Go into airplane mode in weak-signal areas. Or possibly try the UCKE3 modem firmware.

Try flashing att modem. That will help with batt life.

I understand where your coming from, but from any cell phone standpoint 13 hours off the charger and 50% battery left is great! You are on track to Running that battery for over 24 hours, and I don't care what phone you have that's impressive. I have run 2.0 - 2.0.4 and the difference from stock is amazing going From only making it 15 hours and needing to charge now I can make it over a day easy.

Sometimes various sensors like rotation too contribute to the time android system takes up.

[Q] How can I find what's draining my battery?

My sensation currently has a power drain that I can't seem to find the cause for. I'm using InsertCoin 3.4.2 with bricked kernel 1.5, using SPB shell 3D launcher, got an Anker battery, running tasker to cut data, wifi, gps, etc whenever the screen is off, setCPU running ondemand with max at 1536mhz and minimum 192mhz, etc, etc.
I fully charged my phone to 100% about two or three hours ago, and it's been pretty much left alone since. It's now down to 68%.
I've got BetterBatteryStats and SystemPanel, both showing nothing untoward, no active tasks, no wakelocks from what I can tell, etc. And according to the standard app for battery monitoring, it shows the various connections have indeed been turning off as intended, and the phone has been asleep nigh on all the time it's supposed to be.
Any ideas what's going on, or how I could look into it deeper?

I've just been playing with the phone pretty much non stop since I started this thread an hour ago, and the battery level is now at 60%. So that means it's actually consuming MORE power when it's not even in use!

Hi,
There is a lot of talk about battery consumption,and it's causes.
Most people will suggest trying a different kernel,or downclock it to 1.2 GHZ.

I've tried different kernels already, and underclocking the cpu seems to make little difference. As I say, setCPU should be knocking it down to 192mhz whenever the screen is off anyway!

Hi,
Is your ROM a 2.3.4 base or 2.3.5 ?

2.3.5 mate. It's InsertCoin 3.4.2, with sense 3.5 (which I'm not using in favour of SPB).

Hi,
I was going to suggest bricked 0.9.1 with a 2.3.4 ROM,because my son has had great results on his Sensation.
I do not know IC well enough to help.
Sorry.

No problem, thanks for your input anyway.

1)Try his new test version of bricked(beta4).
http://code.google.com/p/bricked/downloads/list
2)Charge to 100
3)Turn off, wait till green, unplug and plugin(bump charging)
4)Boot to recovery thru bootloader and wipe battery stats and then reboot unplugged
Drain you battery to 1, then charge up and repeat for a few days. And you can lower the clockspeed since you're using ondemand, you won't see a speed difference with 1.2 and higher. Oh and use ultra smooth rosie so the home will be faster...And see which apps are open in B/G.

With the exception of trying the beta bricked kernel, I've already done all that when I first got my anker battery. It's not a calibration issue, it's that something is actually draining the battery even when it should be asleep.
And that rosie change isn't needed, as I'm not even using sense in the first place. I've got no real issues with how the phone actually performs as everything is already perfectly smooth. The only slight issue I have is since flashing the amaze camera, on rare occasions it can lock up when exiting it, requiring a battery pull to get going again.

Oops missed the part about SPB, I have been having similar issues but with Faux's kernel after using Amaze cam, but I doubt that could cause sleep drain. I think you drain is caused by the phone not entering "Deep Sleep", some rogue app is keeping the phone partially awake and sucking up juice. I'm gonna go on a hunch and say the phone is running around 1.x GHz while screen if off due to the app.

Hopefully mine can help you. I also noticed HUGE battery drain issues in the past using Bricked Kernel, so I then reverted to stock. Battery was GREAT, but the stock kernel blows. So yeah, I went back to bricked and using the 3rd? beta right now. My battery started dropping like crazy again, so I thought it was the kernel. Before, I used bricked and it was fine so again, I couldn't really blame the kernel. What I tried after that is deleteing my OC app (I've used both SetCPU and System Tuner) and since then, battery is great again! You can try this and hopefully it'll help!

Tried that already as I too suspected the OC app a few days ago. Made no improvements to battery life, so I've put it back on today. Not tried a different kernel yet though, as I'd read that the bricked kernel was the best choice with InsertCoin? I used faux123's kernel first of all, but found it ran hot and kept crashing...
Down to 30% now by the way.

That's what I'm suspecting too, but I don't know how to go about finding it. I've looked with SystemPanel and BetterBatteryStats and haven't spotted anything, but that could just be because I'm not 100% on what to look for. And why would setCPU not be overriding it and making it clock down to 192mhz whenever the screen is off anyway? Isn't that it's job?

Then try the stock and see if it's still draining. When I tried stock and everything was great, I just simply assumed that it wasn't an app. It was the kernel!

I'm not convinced it's the kernel though, as if it was then battery life would have been crap ever since I flashed it. It hasn't been, it's only been bad for the past few days. Are there any links to the stock kernel just in case I can't find anything else?

- mine is 24 hrs
- heavy use 16 hrs
. Used some aninations only
. Turn off wifi when not in use
. Used only 20% brightness
. Used juice defender
. Downclock to 1.2 ghz intellideman
And ofc my kernel and rom that im using right now!
Thank me if I helped

I use bricked and i actually got better batter out of it but itsn still not up to par.. However fauxs ran faster but my phone was getting up to 47C... Way too hot.. I don't know why mines running so hot.. Using coredroid 2.6. 1.5 bricked kernel. wiped dalv and cache and battery stats... blah.. any input? i had setcpu and deleted it.

SetCPU is uninstalled again now to see if it was causing anything, and there's still a drain on the battery when it should be sleeping. Does anyone have any tips on how to find what's keeping it awake? It's been fully charged again, been unplugged for just one hour and it's down to 80% battery. Not even been using it apart from me flashing the InsertCoin Bravia addition onto it, making it 3.4.3.
One thing I have noticed though, is that BetterBatteryStats says the RILJ dialler has been running for 5m 33s since it was last charged, 775 times, 8.9%. This is on the partial wakelocks screen, whatever they are. Everything else listed is under 1%, with the only exception being the alarm at 1.6%. What does this mean?

[Q] battery drains when phone is shut down

my lg g2x drains my battery when turned off
the most previous experience was last night when i had my battery at 39 percent when i turned it off the next morning when i turned it on it was at 19%...
At first i thought it was the faux's DebouchedSloth (the one with the funky readings) so i paid no mind to it. (i just left it on during the night in airplane mode, which actually gave me better battery life) Later, i flashed the trinity kernel, only to find out the same thing happens
what do i do?
im running the latest cm7 kang build from baldwinguy77 with trinity kernel T15max 20122011 if thats any help.
thanks in advance

try a "battery calibration"
let it drain out completely and then let it charge 1 to 2 hours extra after it has reached 100%. worth a shot but i doubt it will help
or try wiping battery status in recovery
also, set up setCPU with profiles

Hmm.. I wonder how the battery drains even though it is off? o_o
Did you try turning it off, than remove the battery and put it back in? And see if it drains.
For me, my battery drains 0% overnight on airplane mode.

I just want to make sure when you say you turned your phone off you mean you shut it down right? I'm just trying to get a answer out of the way because I have seen so many post go a long way only to find out the original post misinterpreted a phrase. If it was in sleep mode a 20% battery drain isn't terrible. I've seen better and worse. If it's draining while it's shut off then I ask are you using the stock battery? It seems to be a big issue and I could easily see it leaking energy while off or giving misread.

there was an article on the xda homepage posted not that long ago. it was about how battery calabration doesnt effect battery life, but only the battery graph found under settings. basicaly it said that the batterystats.bin file only has to do with that battery graph, it tells the phone whats been eating the battery. here it the link if you want to read the article:

anyways back to the point. nope i calibrated my battery a few days ago, so it didnt help

i dont know... and i used to leave it on overnight in airplane mode too with faux's kernel, it drained alot less leaving it on over night then turning it off. but the thing is, leaving you phone on for too long makes it sluggish, so i want to turn it off once in a while to help make it more snappy. I wanted to try that with trinity kernel, but ya thats not really working lool

I would suggest trying a new battery first. I purchased a couple of 3rd party batteries for $20. If it still drains while the phone is OFF, you have some sort of internal hardware problem.

sometimes it's the ROM, i've tried EaglesBlood, PheonixBlood and i get above then norm battery life. I'm on Xboard's OTA and my battery life is sweet

i'm having the same issue as well even when using 2 different batteries and an external charger (for the battery itself).
'normal' drain on the eaglesblood AOSP is about 20% an hour and when I turn off the phone, remove the battery, put it back in, and turn it back on after an hour, the battery drains till it's almost empty!
maxesxp, did the new batteries work? or was it some combination of rom + kernel that did the trick for you?

Weird I just thoughts about looking for this cause I had this happen for the first time. I was at 40% had no charger around so turned the phone off, turned it on the next morning and was at 2% effing weird!
Sent from my LG-P999 using xda premium

My phone does this too. Some days it will drain only a percent or two and others it will drain like 20-30%. From what I can tell the kernel or something is not turning everything off on the phone. Try turning your phone off the next time you do and remove the battery and then when you go to turn it on put the battery back in and see if it drained then. If it did then it is a problem with the battery and if not it is a problem with the phone. If it is the phone there is not much you can do about that, sorry.

P6210 - Huge Battery Drain on ICS

Anyone experiencing battery drain on ICS? I upgraded, rooted, and removed some of the bloatware to help. Thought it was fixed but my tab is dead again. Says the Android OS is taking up my juice. Was never a problem before. Could leave it on standby for days with HC. Now its dead in a day or less.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.

Tried it both ways...wifi on and off.

Try using CPU spy (free in market) or betterbatterystats (free- search for it here on XDA) to see what is eating up your battery exactly.

I noticed that I had a conflict between "Power Savings" settings and the "Display" settings. Putting them both at 1 minute resulted in an always on screen I had to disable the Power Savings to correct the problem.

I did have something odd happen yesterday that seems to have kept my screen on for 4 hours. When I got home and opened my case the tab was very warm, and shut off. And all but entirely out of power, before that it has used about 10 % in 17 hours of standby with about an hour of use, or so.
I think it is possible that an app that previously didn't keep the screen on is now for some reason keeping it on, and I didn't notice when I closed the leather cover.
No issues today, but I am going to try and see if I can find some release notes to tell me about the new download for ICS for the P6210, perhaps this is addressed?

Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.

i suggest checking better battery stats for AudioOut_1 Partial Wakelock. its been draining my phone fast when i upgraded to ICS.
check it here: http://forum.xda-developers.com/showthread.php?t=1629346
now my battery is working great.. i just left my tab for 10 hrs in the locker when i got the tab its still have 97% battery.

for me i just checked and changed my wifi sleep policy from never to when screen turns off and its fine now. :highfive:

I thought about this very issue; I decided to wait.

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.

I had the same problem. i even went back to HC to make sure
the issue is not there (it wasn't) and upgraded to ICS
again (full wipe all the time). No luck something keeps
my device unable to go to deep sleep.
Now i'm back at HC again

The version is OFFICIAL .
It's just available only for some countries.

i had the huge battery drain issue while in stock ICS..
the tablet simply refused point blank to go into deep sleep.. in HC it would but not in ICS.. i would take the tablet fully charged to work and not use it much there.. by the time i was travelling back it would be 60% drained in not using it througout the day...
recently flashed to aorths CM9 build and all my battery woes are gone.. now when i get back from work the battery is at 96%!!
battery drain during usage is the same but the CM9 build has awesome battery conservation stuffs for when you dont use it..
would suggest everyone who has these battery issues to move to CM9.. really helped for me.

Early results show Juice Defender is helping a lot with mine too. Thanks for the tip!
Next morning: Just the free version of Juice Defender using the default profile took me from 35% overnight drain yesterday down to 3% overnight drain today. That's not bad. It should be even better tomorrow because I've turned off all location services after seeing that BetterBatteryStats says Google location is the worst single offender at keeping wifi going overnight.

I had the same exact problem ever since the stock ICS update. My Tab Plus is all stock, no mods at all. The battery would completely drain after one day, and I have very little on the Tab Plus. Nothing helped at all, so I finally bit and did a factory wipe. The battery drain stopped immediately, so I started changing the settings back to the way I like it.
Then, next day the battery went completely dead again! I back tracked and figured out exactly what it is which makes absolutely NO SENSE - turning off wifi in sleep was what was draining the battery! See my screen captures. Notice on the first screen shot, as soon as the wifi stays on the battery drop bar stayed almost flat.
I observed a similar behavior on my 100% stock AT&T GS3 phone also, turning wifi off during sleep causes more battery drain.

I'm getting "suspend backoff" under kernel wakelocks which is preventing my tab going to deep sleep when unused. Everytime I wakeup in the morning my tab is dead. The only solution I found was to turn off wifi if I'm not using it. Anyway fixing this?

The first thing you should do is download BetterBatteryStats so you can figure out what is causing your battery drain.

Have you tried faux123's recommended settings for his kernel? It is on the Faux Kernel Google+ Community. You could also make your own adjustments until you get it how you want it.

ok i have joined it . lets see what happens ,. will post back.. meanwhile can you please tell me about anyother kernel with known working setting

The major kernels are faux franco and bricked. I am on bricked atm but all of them have apps to tweak settings as needed.
If you want battery I suggest bricked or maybe a dialed back franco

Do you have a Pebble by chance? Causes a bluesleep wakelock, other bluetooth devices don't seem to do this. Just a thought since that is the only thing destroying my battery life and I have like 100 apps.

I'm running SlimKat+Faux also and am getting really good battery life. I'm running Faux's recommended settings and as long as I don't use the tap or sweep to wake, the phone sleeps like a baby. I get pretty much crap phone signal everywhere in my area so I don't get massive 5+hour screen on time but it's quite more than enough to take off the charger at 6am and still have around 20% give or take when charging it up at 10pm. Usually getting around 2-3 hours screen on time with about 2-3 hours bluetooth music streaming a day.
